Apple has released iOS 6.1 - it's not a huge release so you probably won't notice much. What is interesting, however, is that Apple has unveiled that after just five months, 300 million iOS devices have been updated to or run iOS 6 - about 60% of all iOS devices ever sold. Google can learn a lot from this, since we're 14 months down the line, and Ice Cream Sandwich is only on about 40% of Android devices. Like I said, trainwreck in slowmotion.

"since we're 14 months down the line, and Ice Cream Sandwich is only on about 40% of Android devices"

There's something you don't seem to get about Android. There's plenty of Android value phones that sell like hotcakes, lke the Galaxy Ace or the Xperia Mini, specially in emergent economies, where also older phones that run 2.x are still being sold (like Galaxy S or Motorola Defy). They are super cheap but there is no way on earth the hardware can run ICS or JB. Because of that, those numbers on global Android OS versions are not very meaningful.

Most people that has phones that can be upgraded to ICS or JB already have upgrades available. The problem is that, even though that, the upgrade cycle for those phones can be really really long like a year at worst. So, yeah in any case, upgrade cycles can be better..
